Plus the cost of taking the aircraft out of service to install them and the extra cost of routine inspections.
West-jet were trying them on their fleet and published some numbers showing the fuel savings had saved about 10% of the cost of installing them.
Mostly because they have very high fleet utilization - so aircraft out of service are very expensive, and they fly mostly commuter routes so spend proportionally less time at cruise where the fuel savings are greatest

-Additional structure required to support them
-Thus additional weight to the aircraft
-Aeroelastic behavior changes
Just a few off the top of my head
